PRESSU RE APPARATUS FOR BEER-BARRELS.

SPECIFICATION forming part of Letters Patent No. 452,010, dated May 12, 1891.

Application filed September 9, 1890- Serial No. 364,472. (No model.)

To all whom, it may concern:

Be it known that I, FRIEDRICH AOKER- MANN, of Brooklyn, New York, have invented an Improved Pressure Apparatus for Beer- Barrels, of which the following is a specifica tion.

This invention relates to an apparatus for forcing air that is both compressed and cooled into a beer-barrel, thus keeping the beer under the proper temperature and pressure.

The invention consists in the various features of improvement more fully pointed out in the claims.

The accompanying drawing represents a sectional elevation of my improved apparatus.

The letter (t represents a water-tank adapted to be filled by a ball-cock a of a watermain and communicating with a reservoir 0 by a pipe I), that reaches nearly to the bottom of the reservoir. The reservoir 0 is provided at the top with an air-cock 'c for replenishing the reservoir with air, and at the bottom with a discharge-cock 0 for drawing off the water. The upper portion of the reservoir c communicates by a tube cl, coil e, and hose f with the beer-barrel g. The coil 6 is placed in a horizontal position, and its lowermost end is coupled to the pipe d at d. Beneath the coupling cl, and consequently beneath coil e, the pipe d is provided with a horizontal section (1*, that receives the products of condensation. These products flow naturally through the inclines of coil e back into the horizontal section (Z of pipe d, and

may be drawn off from time to time through a cock d in section d Thus the products of condensation can never reach the barrel.

The coupling between the upper end of coil 6 and thehosefis made at e. The coil 6 is placed in a refrigerating-vessel h, containing ice, that cools the compressed air as the latter flows through the coil. The hose f is at its other end slipped over a nozzle 2" of the hollow plug or socket i, that enters Through the plug or socket 2'- the barrel g. there extends upward the beerdelivering pipe j. This pipe is provided with the coil j, which is received by the refrigerating-vessel h. From the coil j the pipe j extends upward to the discharge-cock 70 at the bar.

In use water is poured into tank ctto partly fill reservoir 0. As the beer is tapped from the barrel, the air-pressure on tank a will force some water into reservoir 0. The air displaced by the water will, through the pipe cl, coil 6, hose f, and socket 6, enter the barrel As the air flows through coil 6, it will become cooled, and thus the beer will be kept under the proper pressure and temperature. The beer discharged from the barrel through pipe i will be once more cooled as it passes through the coil j.

The tubes Z) cl ej are provided with proper cocks b d e 9' for regulating the flow of water, air, and beer.

WVhat I claim is 1. In an apparatus for cooling and compressing beer and other liquids, the combination, with a compressed-air reservoir, a refrigerating-chamber, and a vessel containing beer, of a coil of pipe arranged in the refrigerating-chamber and having one end connected with the beer-vessel and its opposite end connected with the compressed-air reservoir, so as to deliver air under pressure through the refrigeratingcharnber and. into the vessel containing beer, and a separate coil also arranged in the refrigerating-chamber and having one end entering the beervessel and its opposite end leading to a bar or other placeof draft, substantially as specified.

2. In an apparatus, substantially as described, the combination, with a water-tank, a compressed-air reservoir, a refrigeratingchamber, an d a vessel containing beer or other liquid for use, of a pipe leading from the tank to the compressed-air reservoir, a pipe leading from the top of said compressed-air reservoir to the bottom of the refrigeratingchamber and connected with a coil therein, a pipe leading from the opposite end of said coil to a socket, such as t', in the beer-vessel, a separate coil arranged in the refrigerating-chamber and having one end passing through the socket and into the beer-vessel and its opposite end leading to a suitable point of draft, and suitable valves in said pipes for regulating the flow of air and liquid, whereby the beer in the vessel may be subjected to cold-air pressure while in the vessel and forced through one of the coils in the refrigerating-chamber in its passage to the discharge or draft cock, substantially as specifled.

FRIEDRICH AOKERMANN.
